Effect of the relativistic spin rotation on two-particle spin composition

  • 1. Joint Institute for Nuclear Research, Dubna (Russian Federation)

Description

The effect of the relativistic spin rotation on two-particle states, conditioned by the setting of the spins of the particles in their rest frames and by the noncommutativity of the Lorentz transformations along noncollinear directions, is discussed. Particularly, the transition from the c.m.s. of two into spin-1/2 particles in the laboratory is considered. When the vectors of the c.m.s. particle velocities are not collinear with the velocity vector of the c.m.s., the angles of the relativistic spin rotation for the two particles are different

Abstract (Russian)

Обсуждается влияние релятивистского вращения спина на двухчастичные спиновые состояния с учетом фиксации спинов в системах покоя частиц и некоммутативности преобразований Лоренца вдоль неколлинеарных направлений. В частности, рассмотрен переход из с.ц.м. двух частиц со спином 1/2 в лабораторную. Когда скорости частиц в с.ц.м. не коллинеарны скорости с.ц.м., углы релятивистского вращения спина для двух частиц различны
